IMPROVEMENT IN 'ASPHALTUM OR CEMENT PIPES.

Specification fin'ming part of Letters Patent No. 206,2ZND, dated July 222, 1878; application filed To all 107mm it may concern:

Be it known that 1, MICHAEL ALLEN, of New York, in the county of .New York and State of New York, have invented certain new and useful Improvements in Asphaltum or and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to letters of refer-' ence marked thereon, which form a part of this specification. 1

Figure 1 is a side elevation of two sections of pipe joined together, the joint being sur rounded by a sleeve. Fig. 2 is a section taken online 00 w of Fig. 1. Fig. 3 is a transverse section taken on line 3 y of Fig. I; and Pi 4 is a view showing the veneer being coiled on the inner eylinder.-

This invention relates to certain improvements in pipes for water-mains and other purposes, and' is designed as an improvement on Letters Patent No. 203,869, granted to me *May 21, 1878; and the invention consists in an asphaltum or cement pipe having embedded therein one continuous veneer of any suitable wood, secured to cloth or other fibrous material, said veneer and cloth being coiled one 1. yer upon the other, and in a cross-see tion presenting a volutc surrounded by a bandor coil of sheet metal, which is also our bedded in the asph altum or cement; and the invention further consists in a cast-iron joint formed by two rings having flanges, upon which the veneer is wound; also, in a sleeve surrounding the joint, all of which will be hereinafter more fully setforth. 7.

In the manufactiue of this pipe I form a cylinder, A, of asphaltum or cement, and arrange at one end thereof a cast-iron ring, B, formed with a groove, C, and a flange, D, and at the other end I place a cast-iron ring, E, formed with a tongue, F, a flange, G, and a collar, H. Upon the cylinder A and flanges D and G of the rings 13 and E are wound one or more coils of veneer, I, of an v suitable wood, mounted upon cloth or other fibrous material J, secured to the veneer by liquid asplmltnin or other glutinous substance.

In coiling the veneer the end is first em bedded in the cylinder A, and then wound around to the embedded end, and then upon each preceding coil, forming in a cross-section a volute, as shown in Fig. 3 of drawing. As the veneer is beingcoiled around asphaltum or cement is interposed between each layer.

Upon the coils of veneer is formed a layer of asphaltum or cement, in which is embedded a shcet-metal band, K, which may be coiled around one or more times, the ends extending over and resting on the rings 13 and E, as shown in Figs. 1 and 2 of drawing. This band or coil K of sheet metal is then covered bya layer of asphaltum or cement, K. The pipe is then rolled in sand in order to harden the asphaltum and protect it from the heat of the sun.

The joint of each section of pipe is sur rounded by a metal sleeve, L, to strengthen the joint, and the space between the pipe and sleeve packed, as shown in Fig. 2 of drawing.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an asphal tum or cement pipe,- the combination of a coiled veneer and sheet metal,

as set forth. 7

2. In an asphaltum or cement pipe, the cone bination of a coiled veneer, mounted upon cloth or other fibrous material, and a coil or band of sheet metal, as set forth.

3. An asphaltum or cement pipe having embedded therein'coils of veneer, mounted upon cloth, and a band or coil of sheet metal, in combination with the rings 13 and E and a sleeve, L, as set ,forth.

In testimony that I claim the foregoing as my own I atfi two witnesses.

MICHAEL ALLEN.
